Donor Antenna = The antenna/s that’s usually installed outside building, facing the cell site and “donating” a signal to the system.
Service Antenna = The antenna of a system that’s providing the enhanced signal to a space. Usually referred to an “indoor antenna” when deployed inside a building, or service side of an outdoor system.
OTA = Over-The-Air. This refers to a type of DAS where the input signal is fed to the system wirelessly via an outdoor donor antenna.
WSP = Wireless Service Providers. ie: Verizon, AT&T, T-Mobile.
DAS = Distributed Antenna System. A list of devices and components like antennas, splitters, couplers, coax cables, amplifies, radios and in some cases fiber optics, assembled and connected up in such a way so as to wirelessly distribute an enhanced signal over an open area using multiple antennas. There are different types of DAS’s using different types of distribution methods. Analog vs Digital, Passive vs Active, Copper vs Fiber, Over-The-Air (OTA) vs Backhaul. All of these components listed above are used to create different types of DAS’s. A repeater for example, is not a different solution to a DAS, but is a component that makes up one type of DAS.
Repeaters vs Signal Boosters vs BDA’s = These terms refer to a type of signal amplifier that’s designed to increase the gain of a signal. Repeaters usually indentify to amplifiers that have enough gain to propagate or broadcast a signal wirelessly over a predetermined distance. Whereas s Signal Booster usually refers to an amplifier with gain that’s not powerful enough to wirelessly propagate, broadcast or, “jump” a signal wirelessly off the face of an antenna, and so it needs to be physically tethered to the device it is boosting a signal to. It is important to note that both types of amplifiers are accurately called BDA’s or Bi-Directional Amplifies, (signals enhanced in both directions – Uplink and Downlink).
No, not at all!
Inherently, a cellular repeater is designed to support the frequency bands being delivered by a macro cell-site or small-cell. The serving sector of the cell site that the donor antenna of the DAS is aligned to, usually has a pretty large number of calls it can support at the same time. The JDTECK DAS will also support the same amount of calls. Factors that could impact the number of calls supported (a bottleneck) include; insufficient composite power of the headend unit for the desired area of coverage (not powerful enough), significant increases in the noise floor by the DAS (poor engineering or quality of components), critical frequency bands not being supported (not correctly spec’d), poor azimuth alignments (donor antennas not properly aligned), poor RF power distribution (poor system engineering), to name a few. These are all factors that JDTECK considers when engineering a solution so they do not create a bottleneck for the number of calls our systems can support.
An eFemto is an enterprise-grade radio made available by WSP’s which generates a cellular signal from a high speed ISP connection. It is typically used in applications where the cell towers in the area are over capacity (too many users), or the cell tower are just too far away to extract a good enough signal using high-gain antennas to a DAS. eFemto radios typically support up to 62 simulations users and only support the LTE protocol. An eFemto radio can be used to donate a cellular signal to a DAS. To increase the number of simultaneous users, multiple radios can be annexed together.
Due to its inherent design, eFemto radios require a dedicated highspeed internet connection to work properly. This will add an additonal monthly expense to support a DAS.
Yes! A well-engineered and deployed OTA DAS will ALWAYS deliver a superior user experience (5G Ultra-Wide Services and Speeds) without having to pay for a highspeed internet connection. It is always ON and dedicated solely to supporting mobile phones in the space. WiFi calling is at best, a “band-aid” to delivering mobile phone usage in a space that has poor cellular coverage. It is NOT a substitute for a DAS which many users who critically rely on their mobile phones have come to learn the hard way. In most cases, the Quality-of-Service (QOS) of an organization’s WiFi network, is not set to prioritize Cell-Phone activity, so other devices and services on the network will take precedence over cell phones.
Additionally, using your WiFi network to support Cell Phone usage will bog down your network, forcing organizations to have to pay for additional bandwidth to support the additional load on the network, thus defeating the purpose of trying to save money using WiFi. WiFi calls will drop as you exit the WiFi coverage zone, for example, walking outside the building. Nothing exposes the grave mistake of using WiFi calling in a space, when there is an active emergency event and many persons are desperately trying to make calls. On the other hand, a dedicated DAS is a seamless coverage solution pulling a signal from the same outdoor cell tower. Therefore, as you exit the building, the call remains connected.
Time and time again, a dedicated DAS always proves to be a sustainable, long-term and superior solution over WiFi calling. A dedicated DAS also eliminates the risk of pairing your mobile phones to questionable networks which can track your usage and movements, posing a security risk to the unsuspecting user.
Yes by default, all the major providers are supported with our DAS, however we can pay special attention to extracting the very best performance from the provider that’s of primary importance for your organization.
Yes, we most certainly do! At the end of a system deployment, we conduct system optimization and performance verification testing. We walk the entire space with a representative of your company to ensure they are well pleased with the results and sign off on the project as accepted, before we leave the job site. At the time of system commissioning and optimization, the improved results should be instant, immediate and clearly apparent.
Remote monitoring is strongly advised, especially for higher powered digital systems. In fact, in some markets, network operators will not allow a DAS on-air without remote access capabilities enabled.
As standard operating procedures (SOP), JDTECK offers a 3 Year remote maintenance agreement with all our digital systems. This allows us to clear any system alarms or, promptly respond to any complaints either from the end users or Wireless Service Providers.
No.
Yes of course! We ensure there is more than sufficient distance from any other radio systems or transmitting devices during deployment. This is to protect the performance and integrity of all systems in the space, including WiFi. Additionally, with remote access to the system, we can make any needed adjustments on the fly, should the environment change post our installation.
No, our engineered coverage design takes all these environmental aspects and conditions into consideration. Then at system commissioning, we walk the entire space to document the coverage and performance results to ensure they meet key performance benchmarks. We also do a follow up walk-test with a representative of your organization to ensure they are well pleased with the coverage.
A Signal Booster is designed for hardwired applications whereas a repeater is designed to provide wireless coverage to a specified area. Signal Boosters are typically used in M2M applications while repeaters are used in Distributed Antenna Systems to provide wireless coverage to a specified area.
JDTECK’s Signal Boosters and Repeaters supports all technologies or protocols in the frequency band the device is compatible with. These include LTE, GSM, DCS, CDMA, PCS, AWS, WCDMA, CDMA2000,UMTS, HSDPA, HSUPA, EV-DO, EDGE, and GPRS to list some.
A Line Amp is designed to be installed downstream of a repeater in a DAS (Distributed Antenna System) where signal starts to drop off towards the extremities of the area thus boosting the signal back up to those weak antennas. It has both UL and DL gain, but only DL output power. A signal booster on the other hand is designed to be hardwired to the device it needs to boost or amplify signal to. It is installed between the external antenna and the device boosting both UL and DL gain.
It is important to note that line amps should not be liberally incorporated into a DAS at the design stage but should only be added if the link budget did not quiet produce the desired results after deployment, or a particular area in the DAS needs a small boost in power and a higher powered repeater or additional repeaters would be too costly to achieve this. It is always best to spec an appropriate sized repeater for the area you need to cover from inception.
Gain is defined as the compressing of the vertical component of the antenna pattern, in effect causing the radiation pattern of the antenna to reach out further toward the horizon. It is not the creation of power, but rather a simple refocusing of energy from all directions to a specific direction. Gain is measured in decibels (dB). Vertical antennas are in fact quite directional, except in the horizontal or azimuth plane.
0-dB gain antennas radiate more energy higher in the vertical plane to reach radio communication sites that are located in higher places. Therefore, they are more useful in mountainous and metropolitan areas with tall buildings. A 2dB or 3dB gain antenna is the compromise in suburban and general settings. A 5dB gain antenna radiates more energy toward the horizon (compared to the 0, 2, and 3dB antennas) to reach radio communication sites that are further apart and less obstructed. Therefore, they are best used in flatlands and open areas.
This simply means that if the antenna is vertical, the signal will be transmitted equally in all directions along the horizon.
It depends on your environmental conditions. Clearing any immediate obstructions within 40-50ft of the path of the antenna would be best. These include any walls, building roof line or trees blocking a clear Line of Sight (LOS) to the cell tower. The antenna should also be at least 3-4ft above the obstruction to avoid any reflections that may occur with will affect performance.
The acronym DAS means Distributed Antenna System. It comprises of several components mated together to create a network that distributes signals across a specified area. There is a misconception by many that DAS refers specifically to an active fiber solution, however this is logically incorrect. The word distribution in the acronym DAS would mean any system with more than 1 distribution point. Therefore a system with just 2 service antennas is accurately called a DAS (A Mini-DAS) because you have ‘distributed’ the signal to more than 1 point.
There are two main types of signal distribution systems which are passive and active. A passive DAS solution in the true sense is not entirely passive but does has an active component at the heart of it called a repeater. The repeater is designed to receive a signal from a source point, be it OTA (Over The Air), via a Node / base station or Small Cell. The repeater then filters, amplifies and sends the boosted signal via a coaxial cable out to an engineered wiring grid that consists of coaxial cable, connectors, directional couplers, signal splitters and multiple antennas. The service antenna is the last tangible component of the DAS before the signal then “jumps” or moves from that transmission surface wirelessly out to open space. In a typical active DAS configuration the source signal can also be received the same way, via OTA, node or small cell. The signal then goes to a repeater or some sort or BDA which then connects to what is called a Master Unit. Instead of a coaxial connection to the distribution grid as in the passive configuration, the Master Unit converts the RF signal over to light / optical which then transmits the signal through fiber optic cable out to a distribution hub which then further extends this signal out to Remote Units. These remote units then covert the light signal back to RF which then connects to a wiring grid of components just like the passive system mentioned before. (coax, splitters, couplers, antennas)
One of the main purposes for using an active DAS is to be able to transmit a signal across a very large area using many service antennas with reduced signal loss and quality, that’s because a portion of the transmission was sent over fiber optic cable. Another type of DAS is called an “O-DAS” this simply means an Outdoor – Distributed Antenna System. Again, this can be either passive or active in nature. To recap, DAS simply means Distributed Antenna System. There are passive DAS solutions and active DAS solutions. A repeater is just one component of a DAS and not some sort of different solution from a DAS but is one component of a DAS.
Not at all. There are 4 main components to the system: (1) Outdoor or Donor Antenna, (2) Coaxial Cable, (3) Indoor Repeater or Head-end Unit, and (4) Indoor Service Antenna. You simply need to mount the outdoor antenna on a pole or antenna bracket in an appropriate location, run your length of coax to the base unit, install the base unit on a wall inside the area you want to improve reception to and then connect the indoor service antenna. Most customers get this installation done in an afternoon with some help.
Spectrum Analyzers are available for short tern rental from JDTECK. These are typically rented for 1 week and extended as needed. Technical phone support is provided with your rental at no additional cost so any questions about using the analyzer, test setup or results are answered.
Our Quad Band Digital Line of Repeaters are considerably more advanced than any of our other analog repeaters. Because it is digital it means the user has a very high level of parameter control. This includes, which bands you do or don’t want to support. (700, 800, 1900, 1721 MHz) Also, which blocks within those bands you do or don’t want to support. Up to 2 non-contiguous blocks for 700 and 800 or up to 4 blocks for 1900 & 1721.
Another unique feature of the JDTECK digital repeater is the ability for the user to run the unit in a wide band setting if let’s say they want to support all service providers (Neutral Host) but at the same time can control the output levels of all the signals. The user can also control the gain and thus the output power of the system all from an extremely intuitive and easy to navigate GUI. (Graphic User Interface)
What perhaps is the most liked feature of JDTECK’s digital repeater is that you can access it remotely via any PC or Mobile device via and IP connection and make any changes you need. Trigger points for a wide range of parameters can also be setup in the GUI and automatic email notifications sent to the user. (Up to 5 email addresses) If the optional cellular modem is requested which allows the user to remotely access the repeater over the cellular network as oppose to WiFi, automatic notifications can be sent via SMS as well. (Up to 5 phone numbers)
There are many more advanced features of the digital repeaters which are too many to list here. So we encourage you to visit the product pages for more details.

Another type of DAS is called an “O-DAS” this simply means an Outdoor – Distributed Antenna System. Again, this can be either passive or active in nature. To recap, DAS simply means Distributed Antenna System. There are passive DAS solutions and active DAS solutions. A repeater is just one component of a DAS and not some sort of different solution from a DAS but is one component of a DAS.
Not at all. There are 4 main components to the system: (1) Outdoor or Donor Antenna, (2) Coaxial Cable, (3) Indoor Repeater or Head-end Unit, and (4) Indoor Service Antenna. You simply need to mount the outdoor antenna on a pole or antenna bracket in an appropriate location, run your length of coax to the base unit, install the base unit on a wall inside the area you want to improve reception to and then connect the indoor service antenna. Most customers get this installation done in an afternoon with some help.
Spectrum Analyzers are available for short tern rental from JDTECK. These are typically rented for 1 week and extended as needed. Technical phone support is provided with your rental at no additional cost so any questions about using the analyzer, test setup or results are answered.
Our Quad Band Digital Line of Repeaters are considerably more advanced than any of our other analog repeaters. Because it is digital it means the user has a very high level of parameter control. This includes, which bands you do or don’t want to support. (700, 800, 1900, 1721 MHz) Also, which blocks within those bands you do or don’t want to support. Up to 2 non-contiguous blocks for 700 and 800 or up to 4 blocks for 1900 & 1721.
Another unique feature of the JDTECK digital repeater is the ability for the user to run the unit in a wide band setting if let’s say they want to support all service providers (Neutral Host) but at the same time can control the output levels of all the signals. The user can also control the gain and thus the output power of the system all from an extremely intuitive and easy to navigate GUI. (Graphic User Interface)
What perhaps is the most liked feature of JDTECK’s digital repeater is that you can access it remotely via any PC or Mobile device via and IP connection and make any changes you need. Trigger points for a wide range of parameters can also be setup in the GUI and automatic email notifications sent to the user. (Up to 5 email addresses) If the optional cellular modem is requested which allows the user to remotely access the repeater over the cellular network as oppose to WiFi, automatic notifications can be sent via SMS as well. (Up to 5 phone numbers)
There are many more advanced features of the digital repeaters which are too many to list here. So we encourage you to visit the product pages for more details.
A Signal Booster is designed for hardwired applications whereas a repeater is designed to provide wireless coverage to a specified area. Signal Boosters are typically used in M2M applications while repeaters are used in Distributed Antenna Systems to provide wireless coverage to a specified area.
A Signal Booster is designed for hardwired applications whereas a repeater is designed to provide wireless coverage to a specified area. Signal Boosters are typically used in M2M applications while repeaters are used in Distributed Antenna Systems to provide wireless coverage to a specified area.
JDTECK’s Signal Boosters and Repeaters supports all technologies or protocols in the frequency band the device is compatible with. These include LTE, GSM, DCS, CDMA, PCS, AWS, WCDMA, CDMA2000,UMTS, HSDPA, HSUPA, EV-DO, EDGE, and GPRS to list some.
A Line Amp is designed to be installed downstream of a repeater in a DAS (Distributed Antenna System) where signal starts to drop off towards the extremities of the area thus boosting the signal back up to those weak antennas. It has both UL and DL gain, but only DL output power. A signal booster on the other hand is designed to be hardwired to the device it needs to boost or amplify signal to. It is installed between the external antenna and the device boosting both UL and DL gain.
It is important to note that line amps should not be liberally incorporated into a DAS at the design stage but should only be added if the link budget did not quiet produce the desired results after deployment, or a particular area in the DAS needs a small boost in power and a higher powered repeater or additional repeaters would be too costly to achieve this. It is always best to spec an appropriate sized repeater for the area you need to cover from inception.
Gain is defined as the compressing of the vertical component of the antenna pattern, in effect causing the radiation pattern of the antenna to reach out further toward the horizon. It is not the creation of power, but rather a simple refocusing of energy from all directions to a specific direction. Gain is measured in decibels (dB). Vertical antennas are in fact quite directional, except in the horizontal or azimuth plane.
0-dB gain antennas radiate more energy higher in the vertical plane to reach radio communication sites that are located in higher places. Therefore, they are more useful in mountainous and metropolitan areas with tall buildings. A 2dB or 3dB gain antenna is the compromise in suburban and general settings. A 5dB gain antenna radiates more energy toward the horizon (compared to the 0, 2, and 3dB antennas) to reach radio communication sites that are further apart and less obstructed. Therefore, they are best used in flatlands and open areas.
This simply means that if the antenna is vertical, the signal will be transmitted equally in all directions along the horizon.
It depends on your environmental conditions. Clearing any immediate obstructions within 40-50ft of the path of the antenna would be best. These include any walls, building roof line or trees blocking a clear Line of Sight (LOS) to the cell tower. The antenna should also be at least 3-4ft above the obstruction to avoid any reflections that may occur with will affect performance.
The acronym DAS means Distributed Antenna System. It comprises of several components mated together to create a network that distributes signals across a specified area. There is a misconception by many that DAS refers specifically to an active fiber solution, however this is logically incorrect. The word distribution in the acronym DAS would mean any system with more than 1 distribution point. Therefore a system with just 2 service antennas is accurately called a DAS (A Mini-DAS) because you have ‘distributed’ the signal to more than 1 point.
There are two main types of signal distribution systems which are passive and active. A passive DAS solution in the true sense is not entirely passive but does has an active component at the heart of it called a repeater. The repeater is designed to receive a signal from a source point, be it OTA (Over The Air), via a Node / base station or Small Cell. The repeater then filters, amplifies and sends the boosted signal via a coaxial cable out to an engineered wiring grid that consists of coaxial cable, connectors, directional couplers, signal splitters and multiple antennas. The service antenna is the last tangible component of the DAS before the signal then “jumps” or moves from that transmission surface wirelessly out to open space. In a typical active DAS configuration the source signal can also be received the same way, via OTA, node or small cell. The signal then goes to a repeater or some sort or BDA which then connects to what is called a Master Unit. Instead of a coaxial connection to the distribution grid as in the passive configuration, the Master Unit converts the RF signal over to light / optical which then transmits the signal through fiber optic cable out to a distribution hub which then further extends this signal out to Remote Units. These remote units then covert the light signal back to RF which then connects to a wiring grid of components just like the passive system mentioned before. (coax, splitters, couplers, antennas)
